/*  Arpana Mansfield - ROBOT submission
 * 
 * Assumptions & Comments:
 *      1) More chips would be coming... so making sure that interfaces of the Chip are easy to modify and easy to understand
 *           - the Chip interface could have the "Execute" method as a generic method, however, to simpilified the implementation (because the type would be returned) used an results object instead.
 *      2) Sorting Ascending and Descending... without more requirements, used the constructor to set whether or not the chip would be ascending or descending.  It is possible to have that set within
 *          the "Execute" method, with separate interfaces for each chip to extend the functionality.  If the future chips had similar results and could reuse the return types, then this method is 
 *          probably better.  However, if most of the chips would be creating new return values, then going the generic method route or extending specific device interfaces would be good.
 *      3) Assumed that the array would be changed by the chips.  (Original value not kept)
 *      4) Testing is in the menu as "Run Diagnostics"
 *      5) Used Int[] for array.  However, using a List would make more sense if generics are used.
